The Math Forum has a rich history as an online hub for the mathematics education community. A debt of gratitude is owed to the dedicated staff who created and maintained the top math education content and community forums that made up the Math Forum since its inception.

NCTM will continue to make many of the most popular parts of the Math Forum content accessible to the mathematics education community. We hope that you will
join or continue to be a member of the NCTM community to access even more high-quality resources for teaching and the learning of each and every student.

Problems of the Week

The Math Forum created Problems of the Week as an integrated program that features problems by standard and additional teacher support materials. This database of hundreds of problems and resources is available exclusively to NCTM members.

Notice and Wonder®

We believe that when students become active doers rather than passive consumers of mathematics the greatest gains of their mathematical thinking can be realized. The process of sense-making truly begins when we create questioning, curious classrooms full of students' own thoughts and ideas.

By asking What do you notice? What do you wonder? we give students opportunities to see problems in big-picture ways and discover multiple strategies for tackling a problem. Self-confidence, reflective skills, and engagement soar, and students discover that the goal is not to be "over and done," but to realize the many different ways to approach problems.
